Hello friend, @walictd
Eid-ul-Fitr is a great opportunity for us Muslims to be forgiven by Allah, where this Eid comes after a month of fasting. Allah stops the punishment of the grave for a month of fasting and the punishment starts again from the day of Eid. Many of the family visit the grave on the day of Eid to ask Allah to forgive. The day of Eid is joyful when family and friends meet. Good luck to you friend.
